Procedure
Sonogashira reaction of 25 (3 g, 9.2 mmol) with hex-1-yn-3-ol yielded 2,2,2-trifluoro-N-(3-hydroxy-3-(3-(3-hydroxyhex-1-ynyl)phenyl)propyl)acetamide as yellow oil. Yield (2.31 g, 73%): 1H NMR (400 MHz, CDCl3) δ 7.42 (s, 1H), 7.26-7.38 (m, 3H), 4.86 (m, 1H), 4.61 (dd, J=2.0, 5.6 Hz, 1H), 3.67-3.71 (m, 1H), 3.37-3.46 (m, 1H), 2.38 (d, J=2.0 Hz, 1H), 1.95-1.99 (m, 2H), 1.75-1.88 (m, 2H), 1.53-1.57 (m, 2H), 0.97 (t, J=7.2 Hz, 3H).
